Gene transfer can be readily achieved in zebrafish by microinjection of plasmid DNA or retroviral infection in early embryos. Stable integration of plasmid DNA allows efficient expression of foreign genes either ubiquitously or tissue-specifically, depending on the type of promoter used. Most zebrafish transgenics generated to date have been used in basic embryological research.
